Today in class, we began by watching a http://www.brainpop.com/ video on density. Students learned that density is a physical property that takes the mass of a substance and divides it by its volume. After answered the video questions using the student responders, students were given a reference chart of densities of known liquids and metals to compare the results of their lab. Students calculated the results of their three unknown liquids and three unknown solids from yesterday's lab and compared them to the chart to predict what the substances were.
Overall, I believe it was a very successful lab. Students got to practice their measuring skills again in a practical application. Math skills were applied to determine volume and density. Students had to compare, predict and evaluate their results.
There is no assigned homework, and the Chapter One Test is one week away.
